RAM Shipments
  • RAM shipments are delivered to SBA 329 at HSC for processing. Each package is visually inspected, scanned for surface contamination, and checked against authorized radiation limits.
  • Short-lived isotopes (e.g., F-18) can be shipped directly to the lab WITH prior approval. Email radsafety@usc.edu or call (323) 442-2200 for guidance.
RAM Transfer

RAM can be transferred from other institutions to USC. Email radsafety@usc.edu or call (323) 442-2200 to initiate the process.

What I Need to Know…

  • Contact EH&S at (323) 442-2200 or email radsafety@usc.edu immediately if a RAM package is delivered directly to the laboratory without prior approval.
  • DO NOT place orders directly with vendors.
